What safety practice involves connecting conductors to prevent static electricity in propane work?

• A. Not necessary
• B. Bonding and grounding
• C. Wearing gloves
• D. Keep cylinder cap on at all times

Answer: (B)

Static electricity can build up when propane flows through hoses and across metal surfaces. If two conducting surfaces are at different electrical potentials, a spark can occur when they’re connected, which could ignite propane vapors. The safety practice that prevents this is bonding and grounding. Bonding is linking the metal parts of the transfer system with a conductor so both containers are at the same electrical potential, while grounding provides a path to the earth to discharge any stray charge. Together, they minimize the risk of a spark during connections or transfers. Other safety measures like wearing gloves or keeping the cap on protect against other hazards, but they don’t address static discharge in propane work.
